Applies to vehicles: with removable towing bracket
Safety check
Check that the green marking -6- Fig. 1 on the knob is inside the green zone on the ball joint.
Check that the knob is directly against the ball joint, so that there is no gap -7- between the knob and the ball joint.
Check that the ball joint is locked and the key is removed (so that the knob cannot be pulled out).
Check that the ball joint fits tightly in the mounting fixture (try moving it about to check).
Electrical socket for trailer
The cable of the towing bracket can be connected to the socket Fig. 2.
If the safety check is not satisfactory, the ball joint must be fitted again properly.
